Derby-ER, Astra etc are all SD-10/Pl-12 class missiles +/-, they're not even in the same league as PL-15s.
Indian side has 3x Rafales with Meteors, Pakistani side 3...4x J-10CE and JF-17blk.3s (but the latter aren't combat-ready yet).
Rafales are (somewhat)more capable (and Meteors are longer-ranged), but Chinese fighters and especially missiles will be available in higher/far higher numbers.
But still, it was arguably much worse before for Indian side, because they still haven't moved beyond 1st gen RVV-AE (aim-120b contemporary), against c-series amraam.
Astra is a c-series competitor, after all.
